Cargo Features

Reasonable has no features set by default.

[dependencies]
reasonable = { version = "0.2.1-alpha9", features = ["python"] }
python = pyo3

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
